[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water heater such as an electric water heater or an oil water heater, and more particularly to an improvement of a piping system.

[0002]

2. Description of the Related Art FIG. 11 shows a configuration of an electric water heater A which is a hot water heater, for example, using midnight power, a hot water supply destination B thereof, and a piping device Ca.

[0003] In the figure, reference numeral 1 denotes a water heater main body which is a water heater main body. A pipe connected to a lower portion of the water heater main body 1 is a water supply pipe Pa, and communicates with a water supply source (not shown). A dedicated water stopcock 2 and a pressure reducing valve 3 are provided on the water supply source side of the water supply pipe Pa, and a freezing prevention heater 3a is provided around the pressure reducing valve 3. The above water pipe Pa
Is branched from the middle part and communicates with a mixing faucet 4 with a shower provided in a bathroom, for example.

A hot water supply pipe Pb, which is a pipe, is connected to the upper surface side of the water heater main body 1. The hot water supply pipe Pb is communicated with a hot water tap 5 provided in a kitchen or a washroom, and with the mixing faucet 4 with a shower.

[0005] A relief valve 6 as a safety valve is provided in the middle of the hot water supply pipe Pb.
c is branched. The relief pipe Pc extends so as to face a drainage section 7 provided near the installation section of the water heater main body 1. The pipe connected to the lower part of the water heater main body 1 is a drain pipe Pd, which is provided with a drain plug 8 in the middle and faces the drain section 7. Such a piping device Ca
And an electric water heater A provided with a hot water supply destination B. At a predetermined time, a heating action is automatically performed, and hot water at a set temperature is obtained.

[0006]

The water heater main body 1 has to store hot water heated to a set temperature for a long time, so that the entire peripheral surface of the tank for storing hot water is covered with a thick heat insulating material. It is necessary to have a heat insulating structure.

Further, the hot water supply pipe Pb communicating between the water heater main body 1 and the hot water supply destination B must also have a heat insulating structure since the hot water must not be cooled during hot water supply. However, in order to prevent accidents such as freezing and rupture of piping due to extreme temperature drop in winter, or to prevent dew from adhering to the peripheral surface due to the effect of high humidity, a heat insulating structure will be adopted. FIG. 12 shows an example of a heat insulating structure for the pipe P.

That is, a heat insulating material 10 is wound around the pipe P, and a galvanized iron wire 11 is wound thereon, and the heat insulating material 10 is tightly fixed to the pipe P. Examples of the heat insulating material 10 include glass wool, rock wool, foam polystyrene, hard polyurethane, and crosslinked polyethylene foam. Further, the peripheral surface of the heat insulating material 10 which is in close contact with the pipe P is covered with a cardboard 12 and is wrapped thereon with a tape 13 such as a vinyl tape or a cotton tape.

In actual installation work of the electric water heater A and connection of the piping device Ca, first, the water heater main body 1 is installed in a predetermined portion, and then all necessary pipes P are connected.
Then, after the connection operation is completed, an operation of applying the heat insulating structure to the pipe P is performed.

However, a part of the pipe P connected to the water heater main body 1 and extending in the vicinity of the main body 1 is kept close to the peripheral surface of the main body 1 in order to minimize the space in which the main body 1 is arranged. Is common.

Therefore, the pipe P near the main body 1 of the water heater is wound with the heat insulating material 10 or fixed with the galvanized iron wire 11 because the gap between the pipe P and the peripheral surface of the main body 1 is extremely small. And the work of winding the thick paper 12 with the tape 13 is troublesome, and the workability is poor.

Further, all of the pipes P around the main body 1 of the water heater are not fixed to the main body 1 of the water heater at all and are not protected. There is a risk of accidents such as leakage.

The present invention has been made in view of the above circumstances, and aims at improving the workability of the heat insulating structure regardless of the degree of the proximity of the piping to the water heater main body and the difference in form. Together with secure mounting and fixing
An object of the present invention is to provide a piping device for a water heater that improves safety.

[0014]
